Hydraulic lift through the root systems in Zygophyllum xanthoxylum
(0) Water is the primary factor limiting plant growth in arid ecosystems.Hydraulic lift may be important in desert ecosystems because this phenomenon may enhance or prolong uptake of water and nutrients through roots during periods of water stress.During hydraulic lift, at night, water absorbed through deep roots in moist soil depths and transported into dry soils in upper portions of the profile,may increase the amount of water available to shallow roots.However, hydraulic lift may not occur in all plants.Our study was designed to investigate the phenomenon of hydraulic lift in Zygophyllum xanthoxylum and evaluate the effect of hydraulically lift on plant water transpiration.
